Res-Outdoor Budget: Landscape Area Measurement

Release from the Department of Water Resources, containing a summary table of II, INI, and NI irrigation status classes, as well as horse corral areas, agricultural areas, and pool areas for all urban retail water suppliers. Column J of the spreadsheet is an “irrigable area” calculated as II + 0.20*INI per DWR’s recommendation in the outdoor water use standard ([Recommendations for Outdoor Residential Water Use Efficiency Standard](https://water.ca.gov/-/media/DWR-Website/Web-Pages/Programs/Water-Use-And-Efficiency/2018-Water-Conservation-Legislation/Performance-Measures/ORWUS_STD_WUES-DWR-2021-02_COMPLETE.pdf)). Suppliers need to use the “irrigable area” data column to calculate efficient outdoor water use. Details of urban water use objective calculations can be obtained from [DWR’s Recommendations for Guidelines and Methodologies document](https://water.ca.gov/-/media/DWR-Website/Web-Pages/Programs/Water-Use-And-Efficiency/2018-Water-Conservation-Legislation/Performance-Measures/UWUO_GM_WUES-DWR-2021-01B_COMPLETE.pdf).
